Specification of Letters Patent.

Patented May "4', 1912.

Application filed April 11, 1911. Serial no. 620,311.

To all'whom it may concern: Beit known that I, J OHN F. Bosoum'r, acitizen of the United States, and a resident of Jersey City, in thecounty of Hudson and State of New Jersey, have invented a new andImproved Vehicle-Tire, of which the following is a full, clear, andexact description.

Theobject of the invention is to provide a new and improved vehicletire, more especially designed for use on the wheels of automobiles andother-vehicles, and arranged to provide the desired resiliency withoutthe use of inflatable members to render the tire pu'ncture proof and toprevent .the vehicle from skidding on slippery roadways.

For the purpose mentioned, use is made of a spiral spring coiled intospiral shape and Y bent into annular form, and embedded in a flexiblematerial, with tread blocks of a hard substance, such as emery,carborundum, or

the like, inserted between the convolutions of the spiral spring, andembedded in the flexible material;

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar'characters of reference indicate corresponding parts in all theviews.

Figure 1 is a face view of the vehicle tire, part being in section; Fig.2 is an enlarged cross section of the same on the line 22 of Fig. 1.;and Fig, 3 is a similar View of the same on the line 3-3 of Fig. 1.

A spiral spring A is coiled into spiral shape and bent into annularform, and its convolutions' are embedded in a. tube B, of rubber orother suitable flexible material, and in the peripheral portion of thistube B and between adjacent convolutions of the spring A are arran dtread blocks C, of a hard substance, pre erably emev, carboru ndum, orthe like, the blocks being segmental and tapering, so that the sidesthereof are approximately parallel with the adj acent convolutions ofthe spring A, as will be readily understood by reference to Fig. l. Theinner portion of the tube B is seated on segmental flanges D fastened bytransverse bolts E to the vehicle rim F, and inside of the tube B isarranged a ring'G engaged by radial bolts H extending through the tube Band between the convolutions of the spring A, through the joints of theflanges D and through the rim F to securely fasten or hold the tire inposition on the rim F of the wheel.

By the arrangement described, the desired resiliency is given to thetire by the use ofv the spiral spring A, and by providing the tread ofthe vehicle'tire with the spaced tread blocks C of hard material,-itisevident that long life of the vehicle tire is insured,. and byalternating the rubber of the tube. B with the tread blocks C,thevehicle onwhich the wheel is used is prevented from skidding onslippery roadways.

The vehicle tire shown and described is very simpleand durable inconstruction, and does not depend on inflatable members, and hence isnot liable to be easily injured.

Having thus described my inventionfI claim as new and desire to secureby Letters Patent: I

A vehicle tire, comprising a spring coiled to form spacedconvolutionsand bent into an annular shape, a tube in which the spring is embedded,and tread blocks embedded transversely in the peripheral portion of theSJ In testimony whereof I have signed my tube between adjacentconvolutions.
